change to keydown from keyup; add delayed $updateView

 - There was a perceived lag when typing do to the fact that we were
   listening on the keyup event instead of keydown. The issue with
   keydown is that we can not read the value of the input field. To
   solve this we schedule a defer call and perform the model update
   then.

 - To prevent calling $eval on root scope too many times as well as to
   prevent drowning the browser with too many updates we now call the
   $eval only after 25ms and any additional requests get ignored. The
   new update service is called $updateView
